UIActivityIndicatorView

/*     UIActivityIndicatorViewStyleWhiteLarge,     UIActivityIndicatorViewStyleWhite,     UIActivityIndicatorViewStyleGray,     */    UIActivityIndicatorView *viView=[[UIActivityIndicatorView alloc]initWithActivityIndicatorStyle:UIActivityIndicatorViewStyleWhiteLarge];    viView.center=CGPointMake(160, 300);    viView.color=[UIColor blueColor];    viView.hidesWhenStopped=NO;//动画停止时是否隐藏    [viView startAnimating];//    [viView stopAnimating];//停止动画        [self.view addSubview:viView];

UIAlertView 与 UIActionSheet

UIAlertView *alertView=[[UIAlertView alloc]initWithTitle:@"通知" message:@"明天礼拜五了，大家晚上多多努力，争取在放假前把项目上架。" delegate:self cancelButtonTitle:@"取消" otherButtonTitles:@"确定",nil,nil];       UIActionSheet *actionSheet=[[UIActionSheet alloc]initWithTitle:@"你确定删除么？" delegate:self cancelButtonTitle:@"取消" destructiveButtonTitle:@"确定" otherButtonTitles:@"其他", nil];

 下面是各自的代理：

- (void)alertView:(UIAlertView *)alertView clickedButtonAtIndex:(NSInteger)buttonIndex{    NSLog(@"点击了第%d个按键",buttonIndex);    switch (buttonIndex) {        case 0:                        break;                    default:            break;    }}- (void)actionSheet:(UIActionSheet *)actionSheet clickedButtonAtIndex:(NSInteger)buttonIndex{    NSLog(@"点击了第%d个按键",buttonIndex);    switch (buttonIndex) {        case 0:                        break;                    default:            break;    }}

UISilder

- (void)viewDidLoad{    [super viewDidLoad];    //实例化	UISlider *slide=[[UISlider alloc]initWithFrame:CGRectMake(10, 100, 300, 60)];    //设置左侧右侧轨道的图片，ios7无效    [slide setMinimumTrackImage:[UIImage imageNamed:@"max"] forState:UIControlStateNormal];    [slide setMaximumTrackImage:[UIImage imageNamed:@"min"] forState:UIControlStateNormal];        //设置最大最小值    slide.minimumValue=0;    slide.maximumValue=1;    //设置当前值    [slide setValue:0.7 animated:YES];    //添加响应函数    [slide addTarget:self action:@selector(onSliderChange:) forControlEvents:UIControlEventValueChanged];        [self.view addSubview:slide];                [self.progressView setProgress:0.7 animated:YES];    }-(void)onSliderChange:(id)sender{    NSLog(@"slider:%@",sender);    UISlider *slider=sender;    self.myView.alpha=slider.value;    self.progressLabel.text=[NSString stringWithFormat:@"%.0f%%",slider.value*100];    self.progressLabel.center=CGPointMake(20+280*slider.value, 100);    }

UISwitch

UISwitch *mySwitch=[[UISwitch alloc]initWithFrame:CGRectMake(100, 100, 200, 50)];    [mySwitch addTarget:self action:@selector(onSwitchChange:) forControlEvents:UIControlEventValueChanged];    mySwitch.onTintColor=[UIColor redColor];    mySwitch.on=NO;    [mySwitch setOn:YES animated:YES];        [self.view addSubview:mySwitch];
